“…In British Columbia, a furrow treatment of Temik 10G (10% aldicarb) at 2.2 kg of /ha is recommended for this purpose. But repeated use of aldicarb in areas with sandy soils on Long Island, NY, and in The Netherlands has resulted in contamination of shallow wells with aldicarb including its oxidative metabolites (Enfield et al, 1981; Smelt et al, 1983). Residues of aldicarb have also been detected in groundwater from wells in potato growing areas of Prince Edward Island (Ernst and Matheson, 1988; Lapcevic and Bobba, 1988).…”

Lance 15G (15% cloethocarb) at 2.0 and 4.0 g of ai/lO m of row was applied as an in-furrow band to potatoes (cv. Russet Burbank) a t planting in a silt loam to control the tuber flea beetle, Epitrix tuberis Gentner. Cloethocarb persisted in the soil for more than 64 days, and its disappearance followed first-order kinetics. The calculated rate constants and half-lives were 0.032 d a y 1 and 21.7 days at the low rate and 0.023 day-' and 30.1 days at the high rate. Cloethocarb was translocated readily into potato leaves. The ratio of cloethocarb concentration between the leaves and the treated soil was highest (3.35) in 37-day-old plants and lowest (0.90) in 65-day-old plants. The concentrations accumulated in the leaves were lethal to the adult beetles and effectively suppressed the populations of overwintered adults introduced to treated plants 28-30 days after planting. Almost complete adult mortality occurred within 24 h of beetle release, which resulted in a significant reduction of emergence of the next generation of adults. Control of beetles released onto treated plants 56 and 64 days after planting, however, was less effective.
